Genetic variability of Aedes aegypti in the department of Sucre, Colombia, by analysis of the nucleotide sequence of the mitochondrial ND4 gene.

Introduction. Aedes aegypti is the most important mosquito species in America for the transmission of viruses of dengue, Zika, Chikungunya and yellow fever. Ecological factors as well as chemical controls can affect the genetic composition of Ae.

[First report of the F1534C mutation associated with cross-resistance to DDT and pyrethroids in Aedes aegypti from Colombia].

The main strategy for the control of Aedes aegypti, vector of dengue, chikungunya and Zika viruses, is based on the use of insecticides to reduce its populations. However, their use has led to insect resistance to these chemicals. Objective: To determine the presence of the F1534C mutation associated with cross-resistance to DDT and pyrethroids in A.

[Genetic differences between populations of Aedes aegypti from municipalities in northern Colombia, with high and low dengue incidence].

Introduction: Aedes aegypti is the principal vector of dengue in urban areas. Despite its epidemiological importance, the genetic variability of Colombian populations of this species is unknown.

Objetive: To determine the genetic variability of mitocondrial gene ND4, which codes for subunit 4 of the enzyme NADH deshydrogenase, between populations of Ae.
